In Simpsons Fantasy VI we find out about Lucy who was captured by Mr. Burns's goons not long after she was born, after being given a slave crown, Mr. Burns sent her out on missions in Gaia and Planet R.
Here she's getting her next mission. Kill Oerba Dia Vanille. Why? Well, any person who has played Final Fantasy XIII will know why.
I was too lazy to draw Lucy's proper clothes at this point, of a grey-jumpsuit, and pony-tailed hair, so instead, I just used her regular design.
Vanille's design is credit to Tetsuya Nomura.
